In the logs, when an email is destined for an IP-based virtual domain, the SMTP forwarder uses that domain and IP throughout the logs, from start to finish. When sending out to the Internet, iMail (at least nowadays, it didn't used to) accurately uses the correct IP address and domain name as the source.<br><br>hMailServer documentation and help is not good enough to make clear how to duplicate this behavior, and indeed it does not seem possible to use it to do so.<br><br>If there are any more detailed docs out there than from their own web site on how to do this, then I would love to see them and would likely unreservedly switch to hMailServer. But we regularly support over 100 IP-based discrete domains on one instance of iMail and it works great, behaving like 100 different mail servers throughout.Thu, 14 Feb 2008 17:13:16 GMTngnearhttp://forums.ipswitch.com/Topic36744-10-1.aspxA few months ago I moved off of iMail and onto hMailServer and was so shocked by the reduction in spam that I constantly thought there was something wrong with my mail server. </P><P>Not receiving 60+ spam e-mail every night takes some getting used to but I have learned to like it :D</P><P>It is clear to me that iMail will not be adding this feature even in the upcoming version (10). </P><P>Seems that if I want my clients to also get used to not receiving spam - I will have to move them off iMail as well.</P><P>Unfortunate, as I have been a customer for over 5 years.</P><P>Happy Trails,</P><P>Roderick...Wed, 13 Feb 2008 17:09:31 GMTRoderick Princehttp://forums.ipswitch.com/Topic36744-10-1.aspxHas anyone tried ASSP?</P><P><A href="http://assp.sourceforge.net/">http://assp.sourceforge.net/</A></P><P>Thanks</P><P>DanTue, 18 Sep 2007 15:49:29 GMTpacketheavyhttp://forums.ipswitch.com/Topic36744-10-1.aspxHello Nektar Meletakos, well done, all of your words are correct! :)<P>Hello John T, not all of us are big companies with a lot of traffic.</P><P>In my opinion a professionell solution for SMTP must have Greylisting.<BR>Alt least, using Greylisting is Admin's decision.<BR>In IMAIL there are a lot of features with the option to use it or not.</P><P>I'm asking me, why Ipswitch is blocking so hard to insert the option for Greylisting?<BR>We're not a provider and we won't use a gateway.<BR>We're want software for smart SMTP. <BR>Tips like gateway or utilities from others is not the way for us.</P><P>I think HMailServer is for companies like us a good alternative.</P><P>Kind regards </P><P>Rainer Noa :w00t:Tue, 18 Sep 2007 01:45:00 GMTRainer Noahttp://forums.ipswitch.com/Topic36744-10-1.aspxA few points</P><P>First off in my case we handle around 5000 messages a day, so there is plenty of room for greylisting.</P><P>Secondly, doesn't greylisting help reduce the overall bandwith and CPU to smtp servers. If we take an industry average of over 65% of all emails being SPAM, well then greylisting offloads the processing of all those messages from our servers, if they fall within the greylisting parameters. </P><P>I agree a gateway greylisting device would be great, but for cases like ours small business (100 users) having the ability to greylist from withing the SMTP server as option would be much easier for us rather then investing in a second device for this.Mon, 17 Sep 2007 13:37:27 GMTNektar Meletakoshttp://forums.ipswitch.com/Topic36744-10-1.aspxPicture an Imail server that is processing 150K messages per day. If an average SMTP session takes 7 seconds, that is an average of 12 SMTP sessions open per second. Now lets say you add graylisting with a value of 30 seconds. And lets say for purposes of this conversatation there is 1 SMTP session initiated per second that falls under gray listing. So now we take the average number of SMTP sessions open per second from 12 to 42. We have just trippled the load on the TCP/IP stack and the SMTP service.</P><P>Yes, graylisting is a usefull tool. But like other tools, it can quickly become a problem source as well.</P><P>Many of us firmly feel that these kind of tools/tests would better be suited at a gateway level rather than at the server itself.Mon, 17 Sep 2007 12:57:45 GMTJohn Thttp://forums.ipswitch.com/Topic36744-10-1.aspxI agree no software is perfect, but greylisting seems to be a great way to combat spam, and simple enough to integrate into IMail, I see no reason why it's not already done or at the very least part of the development path.Mon, 17 Sep 2007 11:19:27 GMTNektar Meletakoshttp://forums.ipswitch.com/Topic36744-10-1.aspxShow me the perfect software at the perfect price and I will give you the keys to the London Bridge.Mon, 17 Sep 2007 11:15:30 GMTJohn Thttp://forums.ipswitch.com/Topic36744-10-1.aspxHello from Germany :)<P>Every day checking the smtp-log, I think to myself: "Please, please godvather of IPSWITCH/IMAIL give me Greylisting!".<BR>But my wishes will not heared. :(</P><P>IMAIL is not the cashcow for Ipswitch and the wishes will be wishes.<BR>I'm looking all so to hMailServer!<BR></P><P>Kind regards :)<P>Rainer NoaMon, 17 Sep 2007 04:48:11 GMTRainer Noahttp://forums.ipswitch.com/Topic36744-10-1.aspxWe use Symantec Mail Security for SMTP for mail filtering.Fri, 14 Sep 2007 07:17:30 GMTfrankehttp://forums.ipswitch.com/Topic36744-10-1.aspxI use ORF from VamSoft sitting on IIS SMTP service.Wed, 12 Sep 2007 18:34:42 GMTJohn Thttp://forums.ipswitch.com/Topic36744-10-1.aspxanyone try with a windows based solution?</P><P>I am looking at hmailserver. maybe I can set this up in front of Imail for the greylisting functionality?Wed, 12 Sep 2007 15:22:21 GMTNektar Meletakoshttp://forums.ipswitch.com/Topic36744-10-1.aspxFreeBSB using postfixWed, 12 Sep 2007 14:25:50 GMTbigtunahttp://forums.ipswitch.com/Topic36744-10-1.aspxMay I ask what servers you have installed infront of your IMail?Wed, 12 Sep 2007 14:15:39 GMTNektar Meletakoshttp://forums.ipswitch.com/Topic36744-10-1.aspxwe have 3 servers sitting infront of our imail server that do greylisting. i have found it to be a very good solution to cut out a lot of spam. after the emails pass through greylisting they get forwarded to the main imail server. seems to work pretty good imo.Wed, 12 Sep 2007 14:14:35 GMTbigtunahttp://forums.ipswitch.com/Topic36744-10-1.aspxHas anyone done this. I have been looking at greylisting and it seems to a simple and very effective way to cut down spam. Has anyone had any success in implementing this in an IMail environment?</P><P>I guess it would take another smtp server with the greylisting and then forward all good emails to the imail, right? The only issue I have with that is the outgoing mail. If it's the IMail box that delivers directly there would need to be an MX record of that IP address, thus allowing incoming mail messages to be delivered directly to the IMail server, being as it is the secondary MX. Unless the Imail server forwards everything through the same smtp server handling incoming connections??</P><P>Looking for some real world feedback.Wed, 12 Sep 2007 13:41:51 GMTNektar Meletakos
